RoadRage Gage Datalogging

SDAdapterSDcardWe talked to racers and listened to what they needed. They wanted hours of datalogging capability. We gave it to them. We can log 24 hours on a single 4 gig uSD card.

Easy transport. You can't get much simpler than taking the card out - and moving it to your PC where you can use a uSD to USB adapter (like you would use for most cell phones).


xcelgraphExcelEasy importing and graphing. Pop in the uSD card, open Excel, hit Import .CSV format. The comma separated variable format is by far the most prevalent and easiest to work with. You can be up viewing your data on a graph or in a spreadsheet in 60 seconds from leaving your car. This is a very easy yet powerful process that satisfies the needs of the Racer or the street enthusiast.

 

 

SDCardEasy Activation. How does one wire run to any momentary switch sound? You push it - and an icon pops up that tells you you are datalogging. You push it again and the icon goes away. You have just successfully created a datalog archive. Note that you can also simply roll the trackball to the left to start or stop datalogging with no external switch - but that isn't nearly as cool.

Easy file identification. Race for any length of time and you are going to have 1000 files from 100 races. We came up with a simple and straightforward way of telling them apart... time. We used the internal micro Real Time Clock (RTC) to create datalog files stored by that day - then individual files stored by time. So if you started datalogging your race on January first 2011 at 6:55:22 am. The gauge creates a directory and file called X:\rrgdir\20110101\065522.csv Subsequent files that day would all be contained in that directory. Simple huh? Update Rates? Roughly 4 hertz for all three readings. For single mode data logging where we only log one variable - we go to 10+ hertz.

 

Bit Resolutions? 16 Bit for Exhaust Temp (0-65536 counts), 12 bit for Transmission and Intake temp, Boost, Drive pressure or Turbo Speed (0-4096 counts).
